Title: Continuous sample preparation for liquid analysis - by merging gas flow with liq. flow and vaporising mixture
Inventor: LOFERER JAKOB
IPC: G01N33/18
Filed: 1980-10-03
Abstract: The method for continuous sample preparation for liq. analysis enables the water quality to be monitored under continuous analysis, in partic. w.r.t. the total hydrocarbon content. A continuously flowing liq. sample is continuously mixed with a gas flow. The gas mixture is heated to a temp. between 100 and 500 deg.C and the heated gas and vapour mixture is then analysed. The sample liq. may be water and the added gas flow may be air, synthetic air, nitrogen or an inert gas. The sample flow to be analysed may contain hydrocarbons. The sample fluid passes along a pipe into which a gas flow pipe projects. The pipe carrying the mixture leads to a vaporiser where output feeds an analyser.

Title: Framed slide (transparency) for COM recording systems
Inventor: KAHMANN BERNHARD
IPC: G03B21/64
Filed: 1981-06-09
Abstract: A framed slide for COM recording systems consists of an image carrier on which a tabular form is reproduced photographically, and a frame for inserting into the COM recording system, the frame being constructed as an interchangeable frame. To date, in these special slides, which are also denoted as form slides, a glass or plastic plate coated with photoemulsion has been used as image carrier. The problem here is that in such image carriers the reproduction of the tabular form on the plate is complicated and expensive. It is therefore the object of the invention to render the production of the form slides simpler and more cost effective, the aim being that the frame for the image carrier should be constructed as an interchangeable frame. According to the solution, use is made as image carrier of a commercially available film section (24) which can be fixed in a position in an accurate way in the frame (10) by means of knobs (16) arranged in the frame (10) and of special cutouts (26, 27) in the film section (24). A transparent plastic plate (21) serves as a cover and pressure plate for the film section (24) inserted in the frame (10). <IMAGE>

Title: Sheet material tiles for surface heat exchanger
Inventor: WALTER ECKARD ING GRAD
IPC: F24J2/04
Filed: 1981-07-28
Abstract: The tile is manufactured from sheet material of any kind (Figure 1). It serves to completely cover a building surface, the majority of all tiles surrounding a heat collecting pipe. The manner of laying is overlapping from the bottom upwards. Each individual tile is on two sides fastened directly to the supporting construction. The third side is wedged tight on the counterfold of the neighbouring tile. The plane surfaces of the tile are provided on the underside with a sound insulating and thermal protection layer. The building surface must before laying of the sheet tiles be prepared with the suitable substructure and all the pipework systematically (Figure 6). The main collecting pipes lie in the plane of the battening. By laying the sheet tiles using half-tiles according to the standard and edge and ridge tiles, a uniform attractive building surface is created, with which heat can effectively be obtained from the environment. <IMAGE>

Title: Control for a trailing steering axle in single-element or multi-element vehicles
Inventor: STRIFLER PAUL
IPC: B62D13/04
Filed: 1981-10-02
Abstract: A control for a trailing steering axle in single-element or multi-element vehicles evaluates measurement variables corresponding to the steering angle of the front axle and the speed of the vehicle and generates control signals corresponding to these measurement variables. The control signals are converted in a control device into control movements to be transmitted to the steering mechanism of the trailing steering axle in such a way that, when the speed approaches zero, the locking angle of the wheels of the trailing steering axle essentially corresponds to the reference angle (Ackermann angle) and that in the case of higher bend speeds the size of the locking angle is reduced in such a way that in the case of respectively identical transverse acceleration the intrinsic steering angle remains the same. By means of such influencing of the steering mechanism of the trailing steering axle the vehicle exhibits equally advantageous manoeuvring behaviour and roadholding in different driving situations.
